Where can I find MoriLee 1920 – PA/MD/DE/NJ?

I’m trying to find MoriLee 1920 around the PA/MD/DE/NJ area. But I can’t seem to find it. I tried it on at a place in Hanover, PA but the size was just too small. I think I want this dress but I want to find a larger size to try on to get the full picture before I go & buy it!
